Scientists have observed an increase in carbon dioxide's greenhouse effect at the Earth's surface for the first time. The researchers, led by scientists from the US Department of Energy's Lawrence Berkeley National Laboratory ...

Big clouds get bigger and small clouds shrink may seem like a simple statement, but the myriad mechanisms behind how clouds are born, grow, and die are surprisingly complex. These very mechanisms may be key to understanding ...

In the midst of the California rainy season, scientists are embarking on a field campaign designed to improve the understanding of the natural and human-caused phenomena that determine when and how the state gets its precipitation. ...

Nearly a quarter of the way through their two-year project, a team of scientists deployed to Brazil's Amazon Basin is unraveling the mysteries of how land and atmospheric processes affect tropical hydrology and climate. Their ...

Increases in air pollution and other particulate matter in the atmosphere can strongly affect cloud development in ways that reduce precipitation in dry regions or seasons, while increasing rain, snowfall and the intensity ...

Science is not settled on a bet or a hunch. Measurements and data feed conclusions and provide clarity. Scientists at Pacific Northwest National Laboratory found that two ground-based stations on a tropical island, though ...

(Phys.org) —Last year, the mobile climate-sensing facility called AMF2 spent its days cruising Pacific waters, fixed aboard a working cargo ship traveling back and forth between Hawaii and Los Angeles. Its next stop is ...

With the simple act of watering a plant, humans alter the balance of moisture in soil and the climate. Atmospheric scientists at Pacific Northwest National Laboratory included irrigation in a climate model and found that ...
